Rosemary tips and germination references.

Correction to the rosemary hints. They can freeze–just not way deep like you’d get outside. I think something like 10F is the limit, maybe 15? Does your porch get colder than that? (Prescott AZ where I saw the planters full certainly sees that cold in the winter. They have some snow now.) And keep the plants on the dry side.
As to germination requirements, the wonderful pages from Tom Clothier and Norman Deno’s books are huge, HUGE resources and I wouldn’t be without them. I am always finding some lovely thing I want that won’t germinate easily and they are my two best places to look.
Garden chores for today: snowshoe 1/2 mile to the mailbox to check for seed catalogs and shovel around the greenhouse. Next time it is above freezing I’ll check the pots in there for watering. I keep them on the dry side too as a little water goes a long way when everything is cold. I lose more pots to wet over the winter than I ever do to cold.
Does Talitha ever grow Cardoon? I have read that the shoots taste like artichokes and wonder if that’s true or simply wishful thinking!
